One who walks around in workout or gym-like clothing to give the effect that they have worked out or gone to the gym today or are planning to work out or go to the gym today when in reality they have not or are not going to. One usually does this to make oneself feel better about their physique or to seem like they are physically fit when in reality they have done nothing today.

Look at that girl in the nike shorts, under armour shirt and asics sneakers with a pony tail. She is totally a workout impostor. I didn't see her at the track or the gym at all today.

A person, usually male, with hair-plugs and pectoral implants that places a workout towel on a machine and proceeds to complete one slow, very light set on a different machine with exaggerated form. Then, the same person will walk around the gym for about 15-20 minutes before their next set, hoping to see someone they know that also would rather socialize than workout. They wear very baggy clothing to hide their lack of proportion, especially in the leg area.

There goes the workout impostor, he's only done 2 sets the entire time I've been here, and I'm finished my workout!

That workout impostor would rather socialize and fix his towel than get results.
